This sounds like something that could be tried with a fairly low investment
= a couple of big shop vacuums and some large tubing. Perhaps we could build
a scale model for experimenting??

As far as shunting aside - there are existing diverter valves for pneumatic
mail delivery systems that could be tried...

I still am worried about frictional losses. All pneumatic systems lose a
good deal of energy due to compression heating of the working fluid..
